5 of the best pool gadgets

OverBoard phone case

£22.49, OverBoard
If you don’t fancy shelling out for a brand new waterproof phone like the Eluga, you can imbue your current touchscreen mobile with aqua-shrugging properties by slipping it into this case. Submersible to 6 metres, it lets you use the touchscreen – and even make calls and send texts – from in the pool (or sea for that matter).
